The effect of biofertilizers on cotton development, yield and technological properties

The aim of this study was to determine the effect of biofertilizer application on cotton yield, cotton growth and fiber technological properties. This study was carried out at faculty of agriculture, department of field crops, Siirt University, Turkey during 2017 cotton growing season. The experiment was conducted in randomized complete block design with four replications. Stoneville 468 cotton cultivar was used as plant material. In this experiment Coton Plus and Mega Flu have been used as biofertilizers to increase cotton yield and technological properties as opposed to the utilization of chemical fertilizer. Further, Cotton Plus is mixed microbial fertilizer which contains Bacillus subtilis, Paenibacillus azotofixans while Mega Flu contains three different genera of bacteria Bacillus megaterium, Pantoea agglomerans and Pseudomonas fluorences. The results of study indicated that there were significant differences between biofertilizers applications in terms of seed cotton yield, lint yield, ginning percentage, the number of monopodial branches, but there were non-significant differences observed in terms of lint quality characteristics except elongation. In addition, there were significant differences for cotton seed yield and lint yield. It can be concluded that the bio fertilizer can be used for increasing yield in cotton.
